Enable clocks and power up domains when a get on a domain is made. This (together with initialising a couple of new clocks) helped boot a Radxa Rock Pi 4B from SD card. It's adapted from Linux 5.15.25 and includes parameters for a dozen Rockchip SOCs, but it's only tested on RK3399.
Some of the parameters are for SOCs not even in U-Boot yet. To save a little space it avoids most data for SOCs not configured in the build. It even mentions CONFIG_ROCKCHIP_RK3066 and CONFIG_ROCKCHIP_RK3366 despite those constants not being in Kconfig yet.
